Although an earlier presence cannot be ruled out, findings in the region related to archaic humans date from up to around 700,000 years ago (Acheulean Culture). Thousands of flint tools and weapons have been collected on fluvial terraces (e.g. Madonna del Freddo at Chieti) and near former lakes (e.g. Valle Giumentina at Caramanico Terme and Valle Peligna at Popoli). These testify to the presence of different Homo species over time, ranging from Homo erectus and Neanderthals to modern humans. A site located at Popoli (Svolte di Popoli) also contained animal bones, which in that case was of a hippopotamus. The most important evidence of Neanderthals presence in the region was found in caves in Calascio and dates back to the Middle Paleolithic.

Significant evidence of Upper Paleolithic human populations has been found in various places, including the Fucino depression and Montebello di Bertona, the latter giving its name to a distinctive stoneworking technique called "Bertonian".

After the Mesolithic transition, which was characterized by climate change and a lack of food resources, agriculture was introduced in Abruzzo by Neolithic farmers from the Middle East. A skeleton from Lama dei Peligni in the province of Chieti was dated back to 6,540 BC using radiometric dating.

In Abruzzo and Marche, villages typical of Ripoli culture [it] in the 5–6th millennium BC consisted of huts, and were generally located on fluvial terraces or hills overlooking rivers. In some cases they were defended by a moat. Caves were often used for rituals. They practiced agriculture, husbandry, hunting, fishing, and production of pottery, which was painted or decorated. Other older Neolithic cultures present in Abruzzo are called Impressed Ceramic and Catignano.

The Bronze Age saw the spread of Apennine culture and Subapennine culture in central-southern Italy, including in Abruzzo. The former has been associated with pastoralism, and the latter with agriculture. During the Late Bronze Age, Proto-Villanovan culture emerged in Abruzzo.

There are sites of Iron Age necropoli at Fiorano (Loreto Aprutino's frazione), Campovalano (Campli), Alfedena and Capestrano.

At the end of the Iron Age, Abruzzo was inhabited by different tribes, including those defined by ancient Roman tradition as Sabelli: Oscan-speaking Pentri, Carricini and Frentani, and, more generically, Osco-Umbrian Aequi, Praetutii, Vestini, Marrucini, Marsi and Peligni.

Considered strong warriors by ancient writers, they fought against the Romans in the Samnite Wars (from 343 to 290 BC). Some tribes accepted the alliance with the Romans, whereas others surrendered after the Samnite Wars. Following progressive Romanization, they supported the Romans and contributed to many victories in the 3rd and 2nd centuries BC. They fought again with Rome during the Social War (91–87 BC) to gain political rights and created the ephemeral state called Italia with Corfinio as the capital. After the Social War, they obtained Roman citizenship and in the Imperial period favoured economic activities such as trade and pastoralism. On the basis of a division by Augustus, the territory of what is now Abruzzo was part of "Regio V Picenum" and especially "Regio IV Sabina et Samnium". Much later, the region corresponded to the Valeria province, according to Diocletian decisions, and was among the first to see the arrival of Christianity.

Evidence from archeological sites shows that many cities in Abruzzo date back to ancient times. Corfinio was known as Corfinium when it was the chief city of the Paeligni, and it became the capital of "Italia" against the Romans during the Social War. Today's Chieti has been inhabited since the Chalcolithic era, and was an important center of Marrucini (Teate Marrucinorum). Atri was known as Hatria and Teramo was known variously in ancient times as Interamnia and Teramne. Pinna (today Penne), Anxanum (Lanciano), Hortona (Ortona), Histonium (Vasto), Sulmona and Marruvium (San Benedetto dei Marsi) are among the settlements that are still inhabited, while others are no longer so, such as Cluviae near Casoli.

The region was known as Aprutium in the Middle Ages and, according to a hypothesis, it is a combination of Praetutium, or rather of the name of the people, Praetutii, applied to their chief city, Interamnia, the old Teramo.

After the fall of the Western Roman Empire and the Gothic War between the Byzantine Empire and the Ostrogothic Kingdom, looting and devastation of monasteries and towns followed the arrival of Germanic Lombards in the region. Around 572, the Lombards divided Abruzzo into the Duchy of Benevento and of Spoleto, with Faroald I of Spoleto becoming the first Duke of Spoleto. His successor, Ariulf of Spoleto, annexed other territories: the former territories controlled by Aequi, Marsi, Peligni and Vestini. In the 8th century, Transamund II of Spoleto rebelled against Liutprand, King of the Lombards, but was able to recover his duchy and also to include other remaining territories of former Valeria province.

After the beginning of domination by the Franks, in 801, Teate (today's Chieti) also passed from the Lombardic Duchy of Benevento to the Frankish Duchy of Spoleto. In 843, some territories were separated from the duchy (all the region together with the district of Rieti and except that of Teramo according to Liber provincialis), with Celano as capital. So counts of Marsi from different lineages ruled "Marsia" from 843 to 926. In 871, Louis II of Italy founded, as the Carolingian Emperor, a monastery, which would become very powerful in the history of Abruzzo (Abbey of San Clemente a Casauria). With the rule of Hugh of Italy from 926, the territories were divided: Penne and Teate to Atto I [it], and today's province of L'Aquila to Berardo.

After two attempted conquests from two Norman princes of Capua in Abruzzo, two other Normans, Robert Guiscard and Robert I of Loritello, conquered Teate, Valva and Penne. Later, all Abruzzo was definitively conquered by Norman Roger II of Sicily, and in 1156 his son William I of Sicily had these victories officially recognized by Pope Adrian IV.

As part of the Kingdom of Sicily, Abruzzo was involved in the conflicts following the death of William II of Sicily in 1189, and the territories sided with Constance, Queen of Sicily and Henry VI, Holy Roman Emperor, but after the death of the former in 1198, they were invaded by Otto IV, Holy Roman Emperor. They were also involved in the conflicts between Frederick II (son of Queen Costance) and Pope Gregory IX, including the War of the Keys. The administrative region of Abruzzo was formed in the 1230s, when Frederick II divided his realms into justiciarates, with Abruzzo forming one of them.

The newly founded L'Aquila was destroyed by Manfred, King of Sicily (son of Frederick II) in 1259, and supported in the Battle of Tagliacozzo (1268) the defeat of his nephew Conradin against Charles I of Anjou, the new king of Sicily. Since the last half of the 13th century, L'Aquila took a central role in the region. Abruzzo was divided into Abruzzo Citra (nearer Abruzzo) and Abruzzo Ultra (further Abruzzo) by Charles I of Anjou in the 1270s.

After the rebellion called Sicilian Vespers and the subsequent war, in 1302 the Peace of Caltabellotta divided the former Kingdom of Sicily as follows: Sicily to the Crown of Aragon and the Southern Italian Peninsula (including Abruzzo) still to the Capetian House of Anjou.

The region was profoundly affected during the wars that followed a conspiracy which resulted in the assassination of Andrew, Duke of Calabria, the husband of Queen Joanna I of Naples. Different towns (L'Aquila, Penne, Chieti, Lanciano, Ortona) sided at first with the brother of the victim, Louis I of Hungary. In 1443, Alfonso V of Aragon, King of Sicily, conquered the Kingdom of Naples. In the same years, Abruzzo saw many battles, including the ones associated with the War of L'Aquila. Under the Aragonese rulers, L'Aquila started to become a military center, giving up its political and economic importance to Chieti. This period was characterized by economic decline and the spread of brigandage, but coastal centers were favored by trade with the Republic of Venice's overseas territories.

Shortly after the Italian War of 1494–1495 carried out by Charles VIII of France, the Kingdom of Naples returned to Ferdinand II of Aragon. In this and in the following conflict between the Kingdom of France and the Kingdom of Spain over the Kingdom of Naples, Abruzzo sided with France, but Spain won in 1503 and started to dominate the Kingdom of Naples with its viceroys.

In Abruzzo, the aristocracy vainly tried to regain more control when there was a rebellion in the Kingdom of Naples led by a fisherman named Masaniello in 1647.

At the beginning of the 18th century, the region was affected by destructive earthquakes, which also devastated L'Aquila (1703 Apennine earthquakes) and Sulmona (1706 Abruzzo earthquake), and the War of the Spanish Succession, with the Austrian siege at Pescara in 1707. In 1734, Charles III of the House of Bourbon, King of Spain, ended the short Hasburg Austrian domination, which contributed to large land concentrations in Abruzzo.

In accordance with a general diffidence against the Enlightenment ideas, the Abruzzo population of different social classes rebelled in an improvised way against French invasion in 1798 and 1799. After the proclamation of the ephemeral Parthenopean Republic, they continued to be hostile to French invaders (Sanfedismo).

During the client kingdom (1806 - 1815) of Napoleon, in 1806, Abruzzo Ultra was divided into two, as Abruzzo Ultra I and Abruzzo Ultra II (being divided at the Gran Sasso d'Italia); the same Citra/Ultra I/Ultra II scheme was used for Calabria.

The return of the Bourbons was granted by the Congress of Vienna, while Abruzzo was plagued by decline and brigandage. The House of Bourbon-Two Sicilies established the Kingdom of the Two Sicilies in 1816, and ruled until Italian unification (also known as the Risorgimento).

Many rebelled again in 1821, 1841 and 1848 (Revolutions of 1848), but the ideologies of insurgents were different, and included liberal, Jacobin, or reactionary ideas. During the unification of Italy, in 1860, Abruzzo became part of the Kingdom of Sardinia and, in 1861, the Kingdom of Italy. Some supporters of the Bourbons fought against volunteers of Garibaldi, and later banded with simple criminals to participate for political reasons in brigandage, which would be eradicated years later. However, many accepted the new order without enthusiasm or opposition.

Since 1870, due to its economic conditions, Abruzzo saw massive emigration to other regions and countries, which contributed to Italian diaspora.

During the Italian fascism period, Pescara became an important center for its homonymous port, tourism and trade. With the Second World War, Abruzzo was on the Gustav Line, part of the German Winter Line. One of the most brutal battles was the Battle of Ortona. Abruzzo was the location of two prisoners of war camps, Campo 21 in Chieti, and Campo 78 in Sulmona. The Sulmona camp also served as a POW camp in World War I; much of the facility is still intact and attracts tourists interested in military history.

Despite the high level of destructions and victims caused by the Second World War, there was remarkable development in the second half of the 20th century, which particularly favored Fucino and Adriatic coastal areas.

In the 1948 Italian Constitution, these were unified with Molise into the Abruzzi e Molise region, though in the first draft Abruzzo and Molise were separate, and in 1963 Abruzzi e Molise was separated into the two regions of Abruzzo and Molise. Abruzzo Citeriore is now the province of Chieti. The province of Teramo and province of Pescara now comprise what was Abruzzo Ulteriore I. Abruzzo Ulteriore II is now the province of L'Aquila.

Geographically, Abruzzo is nearly at the center of Italian peninsula, stretching from the heart of the Apennines to the Adriatic Sea, and includes mainly mountainous and wild land. The mountainous land is occupied by a vast plateau, including Gran Sasso, at 2,912 metres (9,554 ft) the highest peak of the Apennines, and Mount Majella at 2,793 metres (9,163 ft). The Adriatic coastline is characterized by long sandy beaches to the North and pebbly beaches to the South. Abruzzo is well known for its landscapes and natural environment, parks and nature reserves, characteristic hillside areas rich in vineyards and olive groves. Many beaches have been awarded the Blue Flag beach status.

In Abruzzo there are two climatic zones. The coastal strip and sub-Apennine hills have a climate markedly different from that of the mountainous interior. Coastal areas have a Mediterranean climate with hot dry summers and mild winters. Inland hilly areas have a sublittoral climate with temperatures decreasing progressively with increasing altitude. Precipitation is also strongly affected by the presence of the Apennines mountain range. Rainfall is abundant on slopes oriented to the west, and lower in east and east-facing slopes. The Adriatic coast is shielded from rainfall by the barrier effect created by the Apennines. The minimum annual rainfall is found in some inland valleys, sheltered by mountain ranges, such as Peligna or Tirino (Ofena, Capestrano), where as little as 500 millimetres (19.7 inches) were recorded. Rainfall along the coast almost always never falls below 600 millimetres (23.6 inches). Pescara has relatively less rainfall (about 700 millimetres (27.6 inches)) than Chieti (about 1,000 millimetres (39.4 inches)). The highest rainfall occurs in upland areas on the border with Lazio; they are especially vulnerable to Atlantic disturbances. Around 1,500 to 2,000 millimetres (59 to 79 inches) of precipitation is typical.

The flora of Abruzzo is typically Mediterranean. Along the coastal belt Mediterranean shrubland Is the dominant natural vegetation, with species including myrtle, heather and mastic. Inland are found olive, pine, willow, oak, poplar, alder, arbutus, broom, acacia, capers, rosemary, hawthorn, licorice and almond trees, interspersed with oak trees. At elevations between 600 and 1,000 metres (2,000 and 3,300 ft) there is sub-montane vegetation, with mixed woodlands of oak and turkey oak, maple and hornbeam; shrubs include dog rose and red juniper. Elevations between 1,000 and 1,900 metres (3,300 and 6,200 ft) are dominated by beech. In the Apennine Mountains at elevations above 2,000 metres (6,600 ft) species include alpine orchid, mountain juniper, silver fir, black cranberry and the Abruzzo edelweiss.

The fauna of Abruzzo is very diverse, including the region's symbol, the Abruzzo chamois (Rupicapra pyrenaica ornata), which has recovered from near-extinction. Common species include Marsican brown bear, Italian wolf, deer, lynx, roe deer, snow vole, fox, porcupine, wild cat, wild boar, badger, otter, and viper.

The natural parks of the region are the Abruzzo National Park, the Gran Sasso and Monti della Laga National Park, the Maiella National Park and the Sirente-Velino Regional Park, as well as many other natural reserves and protected areas.

In 2017, the ancient beech forests of the Abruzzo Lazio and Molise National Park of Europe were recognized as a World Heritage Site by UNESCO, with the region thus gaining its first prestigious site.

Until a few decades ago, Abruzzo was a backward region of Southern Italy. Since the 1950s, Abruzzo has showed steady economic growth. In 1951, per capita income or GDP was 53% of that of wealthier Northern Italy. The gap has since narrowed, being 65% in 1971 and 76% by 1994. The region reached the highest per capita GDP of Southern Italy through the highest growth rate of every other region of Italy. The unemployment rate stood at 9.3% in 2020.

Abruzzo is the 16th most productive region in the country, and is the 15th for GRP per capita among Italian regions.

As of 2003, Abruzzo's per capita GDP was €19,506 or 84% of the national average of €23,181, compared to the average value for Southern Italy of €15,808. In 2006, the region's average GDP per capita was approximately 20,100 EUR. The construction of motorways from Rome to Teramo (A24) and Rome to Pescara (A25), which provided better access to the region, is credited as a driver of public and private investments.

The 2009 L'Aquila earthquake led to a sharp economic slowdown. However, according to statistics at the end of 2010, some signals of recovery were noted. Regional economic growth was recorded as 1.47%, which actually placed Abruzzo fourth among Italy's regions after Lazio, Lombardy and Calabria. In 2011, Abruzzo's economic growth was +2.3%, the highest percentage among the regions of Southern Italy.

From the early 1950s to the mid-1990s, Abruzzo's industrial sector expanded rapidly, especially in mechanical engineering, transportation equipment and telecommunications. The structure of production in the region reflects the transformation of the economy from agriculture to industry and services. The industrial sector relies on few large enterprises and the predominance of small and medium enterprises. In the applied research field, there are major institutes and enterprises involved in the fields of pharmaceutics, biomedicine, electronics, aerospace and nuclear physics. The industrial infrastructure is dispersed throughout the region in industrial zones. The most important of these are: Val Pescara, Val di Sangro, Val Trigno, Val Vibrata and Conca del Fucino.

The province of Teramo is one of the most industrialized areas of Italy and of the region, with numerous small and medium-sized companies, then follows the province of Chieti and that of Pescara, which is also supported by tourism; the Val Vibrata (province of Teramo), on the border with the Marche region, is home to a myriad of small and medium-sized enterprises, especially in the textile and footwear sectors. The Val di Sangro (province of Chieti), on the other hand, is home to important multinationals and a factory belonging to the Fiat (Sevel) group. The area of Valle Peligna (province of L'Aquila) is also home to industries (the famous one of Sulmona sugared almonds), while other areas such as Pescara and Theatine are home to numerous industries, including multinationals (for example De Cecco, Procter & Gamble, Monti & Ambrosini Editori, Brioni, Ennedue and Miss Sixty, mostly concentrated in the industrial district of Val Pescara in the province of Chieti).

Agriculture, based on small holdings, has modernised and produces high-quality products. The mostly small-scale producers are active in wine, cereals, sugar beet, potatoes, olives, vegetables, fruit and dairy products. Traditional products are saffron and liquorice. By the late 20th and early 21st centuries, Montepulciano d'Abruzzo, the region's most famous wine, had become one of the most widely exported DOC-classed wines in Italy.

The region produces about 850,000 quintals of fruit, 5 million quintals of vegetables, 1,600,000 quintals of potatoes, and 5,000,000 quintals of grapes, produced both for eating and for winemaking; the latter is estimated at between 3 and 4 million hectoliters, with the production of wines such as Montepulciano d'Abruzzo in the red and cerasuolo (rosé) varieties, Trebbiano d'Abruzzo, Pecorino and the Chardonnay; oil production, on the other hand, stands at 1,350,000 quintals of olives and 240,000 quintals of oil (Aprutino Pescarese, Pretuziano delle Colline Teramane and Colline Teatine), figures that put Abruzzo in sixth place among the Italian regions; as regards cereals, the durum wheat with over 1.5 million quintals constitutes the main cereal, followed by soft wheat (one million quintals), then barley (0.5 million quintals ); other crops are also grown, among them beetroot (2,500,000 quintals), and tobacco (45,000 quintals).

Tourism is an important economic sector; in the past decade, tourism has increased, mainly centered on its national parks and natural reserves, ski and beach resorts, in particular along the Trabocchi Coast. Abruzzo's castles and medieval towns, especially in the area of L'Aquila, have led to the creation of the nickname of "Abruzzoshire", along Tuscany's "Chiantishire". In spite of this, Abruzzo is still "off the beaten path" for most visitors to Italy.

Very popular with visitors from all over Italy and Europe are the natural parks of the region, such as Parco Nazionale d'Abruzzo, Lazio e Molise, Gran Sasso e Monti della Laga National Park, Maiella National Park, and regional park Sirente Velino Regional Park which every year see thousands of visitors attracted by their unspoiled nature and rare wild fauna and flora species such as Abruzzo chamois, with the region boasting many reserves and protected natural areas and lakes (Campotosto Lake and Lago di Scanno).

In the inland mountain areas there are the ski resorts of Scanno, Ovindoli, Pescasseroli, Roccaraso, Campo Imperatore, Campo Felice, Rivisondoli, Pescocostanzo and Pianoro Campitelli where winter tourism is highly developed and then you can play sports such as alpine skiing, snowboarding, ski mountaineering, ski touring, cross-country skiing and dog sledding. Other trails and facilities are in Passolanciano-Majelletta, Campo Rotondo, Campo di Giove, Piani di pezza, Voltigno, Centomonti, Macchiarvana, Monte Piselli where winter tourism is highly developed and then you can play sports such as alpine skiing, snowboarding, ski mountaineering, ski touring, cross-country skiing and dog sledding.

Also of considerable importance is the summer coastal and seaside tourism, which sees the presence of numerous tourist bathing establishments equipped in various centers of the coast such as Montesilvano, Pineto, Roseto degli Abruzzi, Giulianova, Alba Adriatica, Tortoreto, Francavilla al Mare, Ortona, Vasto, Martinsicuro, Silvi Marina and the Trabocchi Coast.

Finally, tourism for historical and cultural purposes is also important, concentrated above all in the cities of Lanciano, Chieti, Teramo, Vasto, Giulianova, Sulmona, and above all L'Aquila which can boast many monuments, museums, castles and churches (St. Gabriel's shrine and Santa Maria di Collemaggio) of national importance; also Pescara despite being a modern city, boasts monuments, churches and museums of historical importance such as the Birthplace of Gabriele D'Annunzio Museum. In the inland mountain areas there are ancient villages, castles, hermitages, sanctuaries abbeys, and ancient churches.

Abruzzo has many small and picturesque villages, 26 of them have been selected by I Borghi più belli d'Italia (English: The most beautiful Villages of Italy), a non-profit private association of small Italian towns of strong historical and artistic interest, that was founded on the initiative of the Tourism Council of the National Association of Italian Municipalities. These villages are:

• Abbateggio
• Anversa degli Abruzzi
• Bugnara
• Campli
• Caramanico Terme
• Casoli
• Castel del Monte
• Castelli
• Città Sant'Angelo
• Civitella del Tronto
• Crecchio
• Guardiagrele
• Navelli
• Opi
• Pacentro
• Palena
• Penne
• Pescocostanzo
• Pettorano sul Gizio
• Pietracamela
• Pretoro
• Rocca San Giovanni
• Santo Stefano di Sessanio
• Scanno
• Tagliacozzo
• Villalago

Although the population density of Abruzzo has increased over recent decades, it is still well below the Italian national average: in 2008, 123.4 inhabitants per km, compared to 198.8. In the provinces, the density varies: as of 2008 Pescara is the most densely populated with 260.1 inhabitants per km, whereas L'Aquila is the least densely populated with 61.3 inhabitants per km, although it has the largest area. After decades of emigration from the region, the main feature of the 1980s is immigration from third world countries. The population increase is due to the positive net migration. Since 1991 more deaths than births were registered in Abruzzo (except for 1999, when their numbers were equal). In 2008, the Italian national institute of statistics ISTAT estimated that 59,749 foreign-born immigrants live in Abruzzo, equal to 4.5% of the total regional population.

The most serious demographic imbalance is between the mountainous areas of the interior and the coastal strip. The largest province, L'Aquila, is situated entirely in the interior and has the lowest population density. The movement of the population of Abruzzo from the mountains to the sea has led to the almost complete urbanization of the entire coastal strip especially in the province of Teramo and Chieti. The effects on the interior have been impoverishment and demographic aging, reflected by an activity rate in the province of L'Aquila which is the lowest among the provinces in Abruzzo – accompanied by geological degradation as a result of the absence of conservation measures. In the coastal strip, however, there is such a jumble of accommodations and activities that the environment has been negatively affected. The policy of providing incentives for development has resulted in the setting-up of industrial zones, some of which (Vasto, Avezzano, Carsoli, Gissi, Val Vibrata, Val di Sangro) have made genuine progress, while others (Val Pescara, L'Aquila) have run into trouble after their initial success. The zones of Sulmona and Guardiagrele have turned out to be more or less failures. Outside these zones, the main activities are agriculture and tourism. In 2016, the Huffington Post placed Abruzzo in fifth position among the 12 best regions in the world for quality of life.

L'Aquila is both the capital city of the Abruzzo region and of the Province of L'Aquila and second largest city (pop. 73,000). L'Aquila was hit by an earthquake on 6 April 2009, which destroyed much of the city center. The other provincial capitals are Pescara, which is Abruzzo's largest city and major port (pop. 123,000); Teramo (pop. 55,000) and Chieti (pop. 55,000). Other large municipalities in Abruzzo include the industrial and high tech center Avezzano (pop. 41,000), as well as three important industrial and touristic centers such as Vasto (pop. 40,636), Lanciano (pop. 36,000), and Sulmona (pop. 25,000).

• Abruzzo International Airport is the only international airport in the region. Open to civilian traffic since 1996, the number of passengers has increased over the years because of low-cost air carriers' use of the facility. Today, the airport has a catchment area of over 500,000 passengers annually.
• L'Aquila-Preturo Airport is located near L'Aquila, but remains underused.

There are four main ports in Abruzzo: Pescara, Ortona, Vasto and Giulianova.

Over the years, the Port of Pescara has become one of the most important tourist ports of Italy and the Adriatic Sea. Heavily damaged in World War II, it underwent major renovations for some sixty years. It now consists of a modern marina with advanced moorings and shipbuilding facilities. It has been awarded the European Union's blue flag for its services. The port of Pescara has lost passenger traffic because of its shallowness and silting, but its fishery and aquaculture activities are thriving.

There is a significant disparity between the railways of the Abruzzo coast and the inland areas, which badly need modernization to improve the service, in particular, the Rome-Pescara line.

Existing railway lines:

• Adriatic railway runs through the whole of Italy from north to south, along the Adriatic Sea.
• Rome – Sulmona – Pescara
• Sulmona – Carpinone
• Sulmona–Terni railway
• Avezzano railroad – Roccasecca
• Giulianova – Teramo
• Sangritana (Lanciano – Castel di Sangro)

There are three highways that serve the region:

• A24 (Rome – L'Aquila – Teramo) was built in the 1970s and connects Rome with the Adriatic coast in less than two hour-drive. The Gran Sasso tunnel, the longest road tunnel entirely on Italian territory, was opened in 1984.

• A25 (Torano – Avezzano – Pescara) connects Rome with Pescara. The road branches off A24 in Torano, spans across the Fucino basin, crosses the Apennines, and merges with A14 near Pescara.
• A14 Bologna – Taranto known as the "Adriatica", includes 743 km (461.68 mi) of dual-carriage motorway between Bologna and Taranto.
